Contrary to the Administration's characterizations, its "FISA Modernization" bill is not about "updating" the law and allowing surveillance of foreign-to-foreign communications. Instead, it could radically expand the government's ability to spy on Americans without a warrant.

It's highly irresponsible for Congress to even consider this proposal before uncovering the truth about the still-shadowy spying program. In recent weeks, Congress has made strides towards more vigorous oversight and authorized subpoenas for key information, but the proposed bill would short-circuit such scrutiny.
